What people use a crimson screen for
As a saturated color, crimson makes a bold backdrop for product photos, thumbnails and streams, and a strong mood light for a desk or party.
Its low blue-light output also makes it a comfortable screen to leave on at night.
Red screens are the classic choice for anything that has to stay visible without wrecking night vision — amateur astronomers, photographers in a darkroom-style setup and pilots use a dim red field to read by while their eyes stay adapted to the dark. A saturated red also lights only the red sub-pixels of a display, which makes it a fast way to spot a dead green or blue sub-pixel, and it doubles as instant stage, party or "alert" lighting.
As a test pattern, a flat crimson field makes a dead or stuck pixel jump out, and it exercises the red sub-pixel.
